Factors Affecting Performance [Text Block]

How did the Fund perform last year?

• For the period of January 1, 2025, to December 31, 2025, the Applied Finance Valuation Large Cap ETF (the “Fund”) returned 20.41%.

• In comparison, the Morningstar US Market Total Return Index returned 17.35% for the same period.

What key factors affected the Fund's performance?

• US stocks rose in 2025, led by the continued appreciation of megacap technology stocks, especially those impacted by the rapid increase AI investment over the course of the year. The performance of the US benchmark was strongest in Communication Services, Information Technology and Industrial sectors.

• The Fund outpaced the benchmark’s gains in 2025. The Fund benefited from stock selection, primarily in Information Technology, Communication Services, and Health Care, and further benefited by sector allocation, aided by overweighting Communication Services and Information Technology while underweighting Real Estate and Consumer Staples.

• The Fund’s emphasis on avoiding overvalued stocks that are poor stewards of shareholder capital contributed to benchmark outperformance on the year. Overvalued stocks, low profit/high growth stocks and firms with intrinsic value less than book value lagged the overall market, while firms reliant on external financing outperformed.
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of how the Fund will perform in the future.
